Bootstrap support as a function of the minimum CI of sites retained in the data. S: the best topology with the squirrel-related clade at the base of the rodent tree;
M: the best topology with the mouse-related clade at the base of the rodent tree;
C: the best topology with Ctenohystrica at the base of the rodent tree. Seven datasets
were considered: (1) all sites (6,255 bps; CI range 0.0625–1); (2) sites with CI >
0.1 (6,210 bps); (3) sites with CI > 0.2 (5,864 bps); (4) sites with CI > 0.3 (5,432
bps); (5) sites with CI > 0.4 (4,833 bps); (6) sites with CI > 0.5 (4,119 bps); and
(7) sites with CI > 0.6 (4,023 bps).
